The LB11-25-100 is a Spherical Lens (Concave-Concave) type optical component with a base shape of Circular. This lens, sourced from CeNing Optics, has a diameter of 25.4 mm and a center thickness of 2 mm. The effective focal length (EFL) of this lens is -100mm, indicating its concave nature.
The lens features two radii of curvature, R1 and R2, which are -104 mm and 104 mm respectively. These radii, in combination with the EFL, contribute to the lens's optical power and performance. The lens does not have an inner or outer radius, suggesting a uniform curvature throughout.
The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range. The lens is designed to operate at a wavelength of 546.1 nm.
Notably, this lens is uncoated. Coatings are often applied to lenses to enhance their optical performance by reducing reflection, increasing transmission, or providing other desirable optical properties. However, this lens, in its uncoated form, offers a different set of benefits, such as simplicity, cost-effectiveness, and potential compatibility with a wider range of coatings if needed in the future.
